On some systems I get a sparse warning when compiling
tests/test-netlink-conntrack.c
/usr/include/x86_64-linux-gnu/sys/cdefs.h:307:10: warning: preprocessor
token __always_inline redefined
/usr/include/linux/stddef.h:4:9: this was the original definition
The problem seems to be that Linux upstream commit
283d75737837("uapi/linux/stddef.h: Provide __always_inline to userspace
headers") introduced __always_inline in stddef.h, but glibc headers
didn't like that until e0835a5354ab("Bug 20215: Always undefine
__always_inline before defining it.").
This commit works around the issue by including a glibc header before a
kernel header.
Fixes: 2c06d9a927c5("ovstest: Add test-netlink-conntrack command.")
